When asked if he thinks cannabinoids can help control cancer pain, he responds with an emphatic “Possibly yes, possibly no, definite maybe.”. There is inadequate evidence for any benefit of cannabinoids (dronabinol, nabilone, medical cannabis, or THC/CBD spray) to treat cancer pain, pain of.

Evaluation of the effect of 5, 10, 15, and 20 mg of THC in oil capsules by Noyes et al. Out of 10 patients in each cohort, 5 received substantial relief from 15 mg, and 7 patients received substantial relief from 20 mg.
In the second study by Noyes et al. A 60 mg dose of codeine is a standard daily opioid analgesic regimen used in the management of many pain types, including cancer pain This suggests the non-inferiority of 10 mg of THC in comparison to a commonly used opioid treatment.
Evaluation of the efficacy of THC oromucosal spray by Johnson et al. Patients who used THC sprays used an average of 8.
Patients were considered to have reached their optimal dose upon experiencing relief of pain, or the development of side-effects. The doses found to produce significant pain relief include an average of 8. Similarly, Lynch et al. Side effects reported in studies included in this review were consistent with those reported in literature investigating the use of cannabinoid-based therapies for several other indications 7.
Table 2 summarises the five most commonly reported side effects of the five studies. In both studies by Noyes et al. Not all side effects were experienced by all patients, and side effects tended to become more prevalent with higher doses. Common treatment-related adverse events reported by Johnson et al. These were reportedly more frequent in patients receiving the nabiximols extract and the THC only extract, when compared with placebo.
The adverse events identified by Portenoy et al. However, patients also reported that the majority of side effects were transient and mild, and could be reduced through adjusting treatment dose. Side effects did not lead to any study drop-outs 13 - The paucity of clinical data available on medical cannabis for treatment of cancer pain is partly due its classification as a schedule I agent by the Controlled Substances Act in , which restricted its investigation as a potential medical product 8.
However, the few studies that were produced on the use of medical cannabis for cancer pain management have results that suggest it does possess therapeutic potential, and is at least worthy of further investigation. There is a lack of dosing guidelines for the use of cannabinoid-based therapies in clinical practice. The ideal dosage would be one that provides effective pain management, but does not produce intolerable side effects.
However, there are challenges in establishing this optimal dose in the advanced cancer patient population. One of these is inter-patient variability, in keeping with results from studies on narcotics and other prescription analgesics.
As optimal doses were found to vary from patient to patient, physicians need to understand how to determine the correct dosage when prescribing to a new patient. In addition, advanced cancer patients are likely to present with complex symptomologies that make it difficult to accurately assess side effects derived from cannabis treatments, and are often taking multiple concurrent medications.
That said, a number of these studies reported that observed side-effects tended not to be treatment-limiting, and could be controlled through dose titration, with pain relief in as little administration of 2.
This highlights the importance of establishing and validating a titration protocol that will allow researchers to identify effective and tolerated dosages in a safe and controlled manner. Several studies presented in this review were underpowered due to small sample sizes, with three out of the five studies reviewed enrolling less than 50 patients. Therefore, the generalizability of the results may be limited, and future studies on medical cannabis are warranted to establish its efficacy and side effect profile in the cancer pain population.
This includes additional efforts to identify the efficacies of specific cannabis compounds and their combinations, as well as ideal methods of administration through the assessment of relevant endpoints. Subsequent clinical trials should also consider the differences in cannabinoid pharmacokinetics and pharmacodynamics among individuals. Moreover, standardized and validated evaluation and reporting of cannabis-associated side effects is warranted in order to enable more accurate comparisons across studies.
Ultimately, this will contribute to the development of clinical guidelines for the dosing and administration of cannabis as a pain medication for the large population of cancer patients in need of pain management, particularly those for whom alternative analgesics are insufficient, intolerable, or unsafe. Current research shows that there is a potential role for medical cannabis in cancer pain management. However, the scale and quality of studies conducted to date are somewhat limited Therefore, further research is needed to establish the efficacy of medical cannabis, either as an alternative to opiates or as an adjunctive therapy, and to identify the most appropriate methods of administration to achieve optimal therapeutic efficacy with minimal side effects.
This study was conducted in collaboration with MedReleaf. Table 1 An overview of randomized controlled trials RCTs involving medical cannabis for cancer pain Full table. Table 2 Summary of most common side effects Full table. The name of the drug is Epidiolex. These drugs reduce nausea in people undergoing cancer treatments and increase appetite in people living with HIV.
Synthetic marijuana is also the name given to drugs such as K2 or Spice. The adverse effects of these drugs can be fatal. Synthetic marijuana attempts to duplicate the effects of the ingredients in the plant. There is theory that the entire plant has a more profound effect with the different ingredients working together to have an entourage effect.
It is possible to extract full extract cannabis oil FECO from cannabis using grain alcohol or ethanol. CBD is another type of marijuana-based oil that is increasingly popular among people with chronic pain. People can apply lotions, balms, and salves containing cannabinoids to the skin to relieve pain and inflammation.
Transdermal patches that contain cannabinoids are also available and are typically more potent than lotions and salves. Edibles are one of the most popular ways to use marijuana. Edibles involve infusing food, such as cookies, brownies, and candies, with the drug. Marijuana edibles offer an easy way to take marijuana, but the effects of edibles can be difficult to predict. Sublingual administration involves placing a drug under the tongue. The drug enters the bloodstream faster using this method and so it will work more quickly.
Opioids are powerful medications that relieve pain by acting on the nervous system. They are highly addictive, and withdrawal symptoms are not uncommon. In , approximately people died every day in the U. Medical marijuana may offer an alternative to addictive opioids. When researchers surveyed almost 3, medical cannabis users, they found that 30 percent had used opioids in the last 6 months. Of those respondents, 81 percent agreed or strongly agreed that marijuana was more effective alone than in combination with opioids.
In addition, 97 percent said they agreed or strongly agreed that they could decrease their opioid usage when taking marijuana. According to some research, it is as effective as opioids, which are among the most potent pain-relieving drugs. The side effects of marijuana use are usually minimal, especially in comparison with opioid side effects. However, due to lack of regulation for most marijuana-based therapies, the exact composition and quality of a product cannot be guaranteed.
There are several strains of marijuana available, so even if one strain does not reduce symptoms, another may. Typically, it is best for people to keep their dosage low, especially if they are new to using marijuana. Those who wish to use medical marijuana should discuss the risks and benefits in more detail with their doctor and ensure they obtain their medications legally and from a reputable outlet.
